List Methods

Lists are packed with many methods (functionalities). To access a method, write:

some_list.method()

Here is a list of the basic methods:

• append(element) - adds a single element to the end of the list
• clear() - removes all elements from the list

• pop(index) - removes an element at the specified index
• reverse() - reverses the order of the list
• sort() - sorts the list in ascending order

Important Note: The append() method adds a single element. If you try to append an entire list, it will be added as a nested list, which is usually not what you want. For example:

lst1 = [1, 2]
lst2 = [3, 4]
lst1.append(lst2)  # Wrong approach for merging
print(lst1)  # Output: [1, 2, [3, 4]] - lst2 is nested inside!

To combine elements from two lists, use a loop to append individual elements instead.

Here is an example of how to use the append method correctly:

my_list = ["orange", "banana", "apple"]
my_list.append("strawberry")
print(my_list)

This will output ["orange", "banana", "apple", "strawberry"].

Example of the clear method:

my_list = [1, 2, 3, 4, 5]
my_list.clear()
print(my_list)

This will output [].

Example of the sort method:

my_list = [1, 9, 2, 3]
my_list.sort()
print(my_list)

This will output [1, 2, 3, 9].
